Method and apparatus for activating/deactivating run-time determined software routines in Java compiled bytecode applications
Provided is a JIT compiler that changes the status of run-time determined software routines between being activated and deactivated in an application program. Conditional statements which are used at run-time to determine whether such a routine has been activated or deactivated are presented as discrete conditions that always evaluate to a known result by using an invariant flag in the compiled bytecode. The JIT compiler optimises an application program by excluding discrete condition checks. Consequently, if the branch of the discrete condition that will never execute includes a run-time determined software routine, then the routine will be excluded from the JIT compilation and will not form part of the JIT compiled native machine code. A run-time class or code replacement facility is used as a means of activating or deactivating a run-time determined software routine at run-time by changing the value of the invariant flag of said routine. |

Next, the system determines from file meta information that the file is a relational data file, and proceeds to transparently map the file open operation to a corresponding relational database operation by discovering a database service configured to manage the relational data file and then sending a request to open the relational data file to this database service. By transparently mapping the file open operation to the corresponding relational database operation, the system allows an underlying data file to be changed to a relational data file without changing the way the user interacts with the client application and/or data file. |

System and method for automatic speech recognition from phonetic features and acoustic landmarks
A probabilistic framework for acoustic-phonetic automatic speech recognition organizes a set of phonetic features into a hierarchy consisting of a broad manner feature sub-hierarchy and a fine phonetic feature sub-hierarchy. Each phonetic feature of said hierarchy corresponds to a set of acoustic correlates and each broad manner feature of said broad manner feature sub-hierarchy is further associated with a corresponding set of acoustic landmarks. A pattern recognizer is trained from a knowledge base of phonetic features and corresponding acoustic correlates. Acoustic correlates are extracted from a speech signal and are presented to the pattern recognizer. Acoustic landmarks are identified and located from broad manner classes classified by the pattern recognizer. Fine phonetic features are determined by the pattern recognizer at and around the acoustic landmarks. The determination of fine phonetic features may be constrained by a pronunciation model. The most probable feature bundles corresponding to words and sentences are those that maximize the joint a posteriori probability of the fine phonetic features and corresponding acoustic landmarks. When the hierarchy is organized as a binary tree, binary classifiers such as Support Vector Machines can be used in the pattern classifier and the outputs thereof can be converted probability measures which, in turn may be used in the computation of the aforementioned joint probability of fine phonetic features and corresponding landmarks. |

Apparatus and methods for speech recognition
A telephone dialing speech recognition method includes determining a location associated with a cellular telephone from geographic indications provided by the cellular telephone, and selects associated search information as a function of the location. Speech based dialers operating in a car environment often have difficulty determining the digits said since some digits have similar sounding names in certain languages. To improve recognition performance, constraints are added to the recognition process, based on the natural constraints of the dialing process. The method utilizes the selected associated search information when recognizing the incoming speech signal. For speech dialing, if the user defines a location where the phone is used, then the “numbering plan” of that country may be used to constrain certain digits. Such constraining of the speech recognizer significantly improves the recognition results. |

Systems and methods with error resilience in enhancement layer bitstream of scalable video coding
A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included. |

Self-stabilizing and fast-convergent structured peer-to-peer overlays
A self-stabilizing overlay maintenance protocol in structured peer-to-peer overlay system stabilizes any initially connected overlay topology to a correct topology. According to the protocol, a node in the overlay system periodically pings neighboring nodes in the leafset of its routing table, who respond with a pong message containing the recipient's view of the ping sender's leafset. The protocol further conserves connectivity when removing a directed link to another node, by first creating a link to a replacement node that in turn has a link to that node. The protocol uses a ping-pong-notify message exchange to track sink and source sets of the directed links between nodes. The protocol also achieves fast convergence, such as in the partition healing scenario, by leveraging the finger set in the routing table to establish and quickly spread healing points from which the protocol can stabilize the structure. |
